ANTSKIDDYIKNG ATTACHMENT.

Specification of Letters Patent.

'ZZ whom it may concern.'

Y e it "known that l, JOHN CUsrnNe BUT- n.- a citizen ot the United States ot and a resident of Belmond,` fright usefu.. :nprovements .in Antiskidding Attachnie` ot which the following is a specitication. i

My inventionI relates to improvements in antisltidding attachments, and the object of' my improvement is to provide an elastically connected and governed device adapted to be connected to a carrying-Wheel and adaptcd' to be placed in or out of an operative position relative to the Wheel on Which it is mounted. to engage the roadway or surface' enlarged front elevation ot one ot said anti skiddingy attachments, and Fig'. 3 is a similar vien' ot same, the former in a retracted and the latter with an extended position of its slide-bar. Fig. 4f is a side'elevat-ion of the attachment shown in Fig. 3, with parts broken an'ay.

Similar numerals of reference denote corresponding parts throughout the several views. y

rIhese antiskidding attachments are adapted to be removably secured to spokes ot an automobile, traction or other carryingivheel, and each comprises a base-plate or bar 2 having' removable clips 13 inserted through orifices near its ends to have their 1U-shaped parts extend toward the Wheel and embrace a spoke thereof, and being secured by nuts on the opposite side of the plate. The plate 2 has an end lug 10 and a medial transverse lug 4- on its outer face, both having' bearing orifices in alinement to receive a slide-bar 3 therethrough. The lugs are long enough to permit the slide-bar 3 to play 'adially past one tace of the Wheel to Whose polie 1 the plate is attached, as shown best aid Fig'. 1. `t is evident, that my attachment may be oca'ted on a spoke, when desired or neces- Tovva, have invented certain new andA sary, as when the-device is'employed on a traction-wheel havingr a broad tire, to have the outer end of its slidable-bar 3 pass movably through an orifice in the tire to engage the surface traversed, Without departing from the principle or scope' of my invention.

The inner endotthe bar 3 is transversely orificed to -receive short bolt 14 luwing` a nut 16 thereon. A small Washer 17 is sea ted on said bolt between the nut 16 and the bar 3, and a coiled spring 18 is seated about the bar and has a portion extended inwardly enough to be coiled two or three times'about the bolt 8, Which secures it in place. rt`he Washer 5 on the bar 3 serves as a seat for the spring 1S. A coiled spring 7 is connected between the bolt v14 and a link 6, the latter connected to a ring 12 encircling' the bar 3 between its lugs 4 and 10, slidably.

9 is a fixed hook on the side oi' the lug 10, and over which the link 6 may be engaged as shown in Fig. 3.

The nuts 8 are locked by means ot Wedges driven into thesplitends ot' the clips 13.

It will be seen, that When the nut 16 is engaged by the end of the spring' 7. the latter being under tension by reason of its connection to the hook 9, said nuthas one corner projected into the hollow end ot the spring and isy held2 there so -that it may not' Work ott the bolt 14.

Instead of a coiled spring 18 about lthe bar 3, otherV elastic bearing-means may be employed such as a rubber sleeve or Washer, but I consider the spring preferable in practice.

As many of these attachments may be placed upon the spokes of a wheel as desired, but preferably there should be placed one on each alternate spoke for better results. lVhen it is not desired to have thebar extended, as When driving over a 'ood pavement, the bar is to be pushed 1 slidably through the lugs 4 and 10 and given apartial rotation, after rst releasing the spring Jtrom the hook 9, to bring the end of the .bolt- 14 'over theend of the plate 2., Where it becomes seated in a notch 11. The spring` 7 then holds the bar With the bolt engaged in said notch since the ring 12 still holds the spring under some tension, until it is desired to. extend the bar, when the bolt may be disengaged from the notch, the spring re-connected to the hook t), and the springwill react to throw the bar out to the extended position. When the bar 3 is extended it will Patented Feb. 25, 1913. l

project a short distance beyond the outer edge of the tire of the wheel, and sufficiently to penetrate the ground where it is rutty, or otherwise dicult to traverse, and, give the wheel a good 'grip to enable it to move thereover Without skidding or slipping. The same result obtains in passing over slippery or icy surfaces of pavements, since the ends ot the bars 3 engage the surfaces passed over to prevent slipping, and in the case of moving over pavements, the bars will move in.- wardly somewhat against the tension of the compression springs 18, which will prevent damage to the pavement, while still alilowingthe devices to properl and eiiciently engage the surface passe over. To disassemble the parts, the spring 7 may be unfastened from the hook 9, and then sprung in enough to permit its other end to slip away from the nut 1G, to permit the nut to be removed.

The devices may have their trame-plates 2 made of aluminum which will not rust and have less weightI than steel. They are inexpensive, easily applied or removed, and may be quickly adapted for extension or retraction as desired.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is:

1. An antiskiddingV attachment for automobile or other wheels, comprising a baseplate having means for securing it to a rcarrying-wheel, said plate having bearingseats thereon, a bar slidably mounted in said seats, said bar having a pin projecting laterally to one side, engaging-means on said plate, and a tension-spring detachably connected between said pin and said engagingmeans adapted to vieldingly project said bar beyond the tread ot' the wheel.

9.. An antiskidding attachment for automobile or other wheels, comprising a baseplate having means for securing it to a carrying-wheel, said plate having bearingseats thereon. a bar slidablv mounted in said seats, said bar-having a lateral projection, engaging-means on said plate, a tension spring detachably secured between said projection and said engaging-means and. adapted to vieldingljr project one end oit the bar beyond the tread of said wheel, and means ttor detachably securing said bar to said plate in a retracted position to not project beyond the tread of the wheel.

maaar/1 3. An antiskidding attachment for auto'- mobile or other wheels, comprising a baseplate having meansfor securing it to a carrying-wheel, said plate having bearingseats thereon, abar slidably mounted in said seats, said bar having'a lateral projection, a compression-spring engaged between said projection and one ot said seats, engagingmeans upon the other of said seats, a tension-spring detachably connected between said engaging-means and the saidprojection, and said tension-spring being adapted to project the end of said bar beyond the outer line of tread of saidwheel.

erin antiskidding attachment for automobile or other wheels, comprising a baseplate having means for securing it to a carrying-wheel, said plate having bearingseats thereon, ajbar slidably seated in said seats, said bar having a transverse orifice through its inner end and a bolt seated therein to project laterally with a nut removably seated on its threaded outer end, engagingmeans. on one of said seats, a tension-spring detachably connected between said engagingmeans and said bolt and adapted to yieldingly project said bar beyond the tread of the wheel, said nut so engaging the adjacent end of said spring as to be locked therewith.

5. An antiskidding attachment for automobile or other wheels, comprising a baseplate having means for securing it to a carryingwheel, said plate having bearingseats thereon, a bar slidably seatedI cin said seats, said bar having a transverse orifice in its inner end with a bolt seated therein having a nut on its threaded outer end, a hook on the bearing-seat adjacent the outer end of -said plate, a tension-spring detachably connected between said bolt-end and said hook, a compression-spring seated about said bar between said bolt and the adjacent bearing-seat and having one end coiled also about said bolt` and means for detachably securing said bolt to the inner end of said baseplate to hold said bar retracted upon the plate to have its outer end withdrawn within the line ot tread of said wheel. l
